    Some weeks back, Allison Parent wrote about some mods for the AMPRO LITTLE
    BOARD-I to improve performance.
    
    These were interesting, but now I'm looking for published mod's for the
    Ferguson BIG-BOARD, which was quite popular, but had only Single-Density
    floppy support via a WD 1771 and which used a standard (2.5 MHz) Z-80.  I'm
    interested in finding out whether there are any published modifications,
    supported with code, to enhance this board's speed, and to upgrade its FDC
    to a 179x type using both FM and MFM.
    
    I've got aboug half a dozen of these boards and want to know that there's a
    way to fix them up before I pass them on to interested parties.  Does anyone
    know of a reliable source of such material?
